The Tuscan cities followed at a distance the example of their northern neighbours. It was their chief concern to wrest municipal privileges from the feudal marquises, who had up to this point ruled town and country alike. Even more conspicuously than the inland towns, the maritime cities attained wealth and freedom. Pisa, Genoa, and Venice obtained, as we have seen, a great position in the East from the time of the First Crusade. While Venice stood apart, proud of its dependence on the Eastern Emperor, the life of the other maritime cities was much the same as that of the inland towns, save that it was more bustling, tumultuous, and varied. Before the end of eleventh century, Pisa and Genoa had driven the Saracens out of Corsica and Sardinia, and set up their own authority in their stead. The free, restless life of the Italian commune offered a splendid field for the intellectual revival which we have traced in the preceding chapter. Side by side with the development of Italian municipalities, went the growth of the famous schools of Italy. The Italian scholars were for the most part townsmen, laymen, and lawyers. While the students north of the Alps became a little cosmopolitan aristocracy of talent, living in a world of their own, and scarcely influenced by the political life around them, the Italian students easily became politicians and leaders of men. Abelard led no revolt save against the tyranny of authority and teachers of obsolete doctrine. His chief Italian disciple became the first educated popular leader known to the mediæval world. With the influence of Arnold of Brescia the gulf between the new life of action and the new life of speculation was bridged over.
